Download link: https: //www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
Elasticsearch because the version I installed is 2.4.1, the installation of JDK == 1.8, the version 2.x ES will use haystack incompatibility.
installation steps:
# First:
cd / usr / local /
mkdir javajdk
# upload the downloaded file to:

# extract the files to this folder
tar-xzvf the JDK-8u231-Linux-i586.tar.gz
mv jdk1. the Java 8.0_231
# configuration environment variable:
vim / etc / Profile

export JAVA_HOME=/usr/local/javajdk/java
